The MAX1920EUT+T is a low-voltage, 400mA step-down (buck) DC-DC converter available in a 6-pin SOT-23 package. It provides efficient regulation for output voltages as low as 1.25V, supporting input voltages from 2.5V to 5.5V. This device features a proprietary current-limited control scheme achieving over 90% efficiency, with high switching frequency up to 1.2MHz, allowing the use of small, low-cost external components. Internal synchronous rectification enhances efficiency and eliminates the need for an external Schottky diode. The converter includes an internal digital soft-start to limit inrush current at startup and reduce input capacitor requirements. It is suitable for use in wireless handsets, PDAs, portable devices, and power supplies for CDMA applications. Operating temperature ranges from -40°C to +85°C. Quiescent current is approximately 50µA, with a logic-controlled shutdown current of 0.1µA. The output voltage is adjustable, with an initial accuracy of ±1.5%, and can be set between 1.25V and 4V at an input of 4.5V.
